[PATCH 1/2] Bump to autoconf 2.69 and automake 1.15.1

Thanks very much for taking on this task.

You do not appear to have updated the AC_PREREQ macro statements in the
various */configure.ac files.  Is this intentional ?

Also the config/override.m4 file still contains a hard coded requirement 
for autoconf 2.64 exactly.

The patch did not include renamed *.texinfo files, although that was
simple enough to fix.

Otherwise so far, my testing has been showing no signs of any real problems.

Cheers
